Nisit was very attentive and swift in responding to our questions prior and through out our stay.
Locationwise, I would say it is very convinient for me as there are shops nearby i.e. 711, Big C etc. It is easy to grab food as well throughout the day as there are alot of vendors nearby selling all kinds of Thai street food. On the weekends, you can visit the Chatuchak market which is around 100m away. There is also an awesome place nearby to eat vegeterian food as well, a plus for my brother who travelled with me on this trip (who happens to be vegeterian), which is run by The Vegeterian Society Chatuchak.
Nisit's place is also located nearby the BTS Saphan Kwai (less than 100m approx), which makes it a bonus for me!
The place however is located at the top floor, so expect some fairly good climbing on the stair cases. But other than that, I have no other complains.
Will definitely stay here again the next time Im in town!
